Down branch fiber fabric and the fabricating method thereof

ABSTRACT

This invention relates to a kind of down branch fiber fabric, its fabricating method and device. The fabric is composed of 10-100% down branch fiber and 0-90% textile fiber by weight. The processing steps include material choosing, silver feeding, twisting, winding packages, heat setting and weaving. The device comprises a raw material tank, a feeding conveyer belt, a inclined feeding conveyer belt, a adjustable even roller, a brambly catching roller, a first subsiding room, an even roller, a brambly dividing roller, a second subsiding room, two dust cages. The present invention makes the down branch fiber spinnable and weavable. It solves the problem that the down branch fiber cannot be combed and drawn and drafted by the prior textile technique, so that chances the fact that the down branch fiber can only be used as the fiber stuffing to make down garments, quilts, ticks and other bedding. This new fabric is applicable to make thermal woven, hoses, quilts, ticks or other bedding.

FIELD OF THE INVENTION

The present invention relates a kind of textile technology for down branch fiber, more particularly the present invention relates a kind of down branch fiber fabric and its fabricating method.

BACKGROUND OF THE INVENTION

Feather and down are all good natural heat-retaining materials. Feather has a flat shape with parallel barbs grown on quills in rows. Down has a shape liking cloud and down can be sorted as down-feather and semi-plume. The down feather has a fluffy structure with little shaft or no shaft. The semi-plume has a fluffy structure too, but it has well formed shaft. For these characters, the feather and down cannot be sorted as fiber. Using common technology, we can separate barb-fibers of the feather or down-branch-fibers of the down or semi-plume from their quill or shaft to get separated barb-fibers or down-branch-fibers. The barb fiber has a same structure as the down-branch-fiber but is coarser than the down-branch-fiber. The barb-fiber and down-branch-fiber both are defined as down branch fiber thereafter. Since down branch fiber has very tiny barbules and hooks distributing equally along fiber, the down branch fiber is considered as a kind of unique nature fiber with many merits, for example, soft, light, heat retaining, etc. However, to us common textile technologies such as combing, twisting, draughting to process down branch fibers is very difficult since the down branch fibers are non-crimp, fluffy, and very short, most of them are around 15 mm to 25 mm. This is the main reason that people use feather, barb-branch-fiber and down branch fiber as stuffing materials for making down garment, quilts, ticks and other bedding only.

Chinese Patent Publication Number CN1222591A titled “Down Branch Fiber Fabric and Its Fabricating Method” and Chinese Patent Publication Number CN1293270A titled “Down Shell Fabric” described a kind of spinning method for the mixture of downs or down-branch-fibers with textile fibers.

According to the common knowledge in the down products industry, down is short, soft fluff got from feathers of waterfowls, such as geese, ducks and the like. Down also means a mixture of down, feather, barb-fiber, down branch fiber and other impurity, in which the ration of down must be over the lowest standard stipulated by this industry. The “down” described in the above-mentioned two patent publications is not a kind of material having same structure, it can't be considered as fiber too. Where, the fiber means a kind of natural or synthetic thin filiform textile material only. Downs can't be used as textile materials for spin directly. If spinning the mixture of downs with other textile materials for yarns, it is impossible to get smooth and uniform yarns since down is fluffy and mixed with other impurity, such as feather and barb-fibers. During processing downs will be blown away since downs can't be mixed with other textile fibers as a uniform combination.

SUMMARY OF THE INVENTION

The purpose of the present invention is to provide a fabricating method for making fabrics from down branch fiber directly; also the purpose of the invention is to provide products made by the fabricating method, i.e. down branch fiber fabrics with strong tensile strength.

The above-mentioned objects are achieved by:

Down branch fiber fabrics are made by mixing down branch fibers with textile fibers, having a blend ration by weight of down branch fiber 10-100%, textile fiber 0-90%.

The down branch fibers are got from handling downs and feathers, which are gathered from waterfowls such as geese, ducks and the like. Cut quills and shafts off from downs, semi-plumes and feathers, then get down branch fibers.

Textile fibers are selected from at least one of nature fibers including cotton, wool, ramie fiber or synthetic fibers including terylene, acrylic, nylon, polyvinyl chloride, spandex, vinylon or chemical viscose fibers.

The method for producing down branch fiber fabrics having following processes: screening raw materials, feeding raw materials into sliver feeding device, twisting, winding packages, heat setting and weaving. The temperature for heating setting is from 80° to 120° C., heating time is from 5 to 20 minutes.

The sliver feeding devise comprises a raw material tank, a feeding belt conveyer, an adjustable even roller, a brambly catching roller, a first subsiding room, an even roller, a brambly dividing roller, a second subsiding room. All these sub-devises are connected and communicated. Discharging port with a bar shape cross section is connected with dust cages coincidentally.

The present invention possesses many advantages comparing with common technologies in this field:

A. The sliver feeding devise has the brambly catching roller and the brambly dividing roller to comb the down branch fibers twice; has the adjustable even roller and the even roller to control the feeding quota of down branch fibers equably around all process; has first and second subsiding rooms to subside the raw materials twice in smooth and equal quantity to ensure that the down branch fibers can pass through the discharging port uniformly. With above-mentioned devises, the present invention solves the difficulties for processing down branch fibers, i.e. non-crimp, fluffy and can't hold together. Therefore, the difficulty for producing down branch fibers as yarns with current processing (combing, twisting, and drafting) is overcome. The present invention finds a way to use down branch fibers to produce yarns directly without a crimp treatment or a denaturation treatment. Thus, the new devices avoid breaking or damaging down branch fibers during process. Therefore, textile products made by down branch fibers become a reality.

B. Since the present invention adapts reel heat Setting, the shortcomings of down-branch fibers, such as non-crimp, restoring original shape, anti-twisting, low tensile strength, etc. are overcome.

C. Down branch fiber is a kind of nature abnormity fiber. It is light, heating-retaining. The fabrics made by down branch fiber keep these good merits too.

D. The present invention provides bright future to use down branch fibers to fabricate different types of pretty and decent products.
